Post Subject: Re: Getting started : MelquiadesPosted by jessie.dazzle on: 7/24/2006
Romy,

I too was thinking the subject had evolved to the point where the thread needed splitting off.

I agree with you regarding the need to start off by constructing of a pair of “normal” Melquiades as a reference.

I don’t mind the fact that a 5-channel project would be labor intensive.

In both cases, I will start off by assembling all the components zip-tied in open-air to their supports (non-conductive panels).

As for sourcing the parts locally : I am very much in favor of experimenting once up and running, but it may be smart to establish a reference using the “Approved Suppliers”, and trying other components later on.

There are a few good shops in Paris that have shelves and drawers full of components. And, across the channel :

Regarding the architecture of the 5-Channel beasts : I should start off by confessing that I am not at all an electrical engineer. I will need to think and ask advice regarding the details. In the prototype stage, though it might be more costly, I have a strong preference for keeping things as direct as possible, dedicating components to only one channel. This approach has the advantage of being easier to get one’s mind around exactly what he might be doing.

As for general architecture/packaging (5-Channel amps) : For reasons of weight (if not for theoretical sonic advantages), dual chassis monoblocks would seem the best choice.

For cooling, I will need to consider the fact that I live with two cats (yesssss), and a fan would likely require an external filter, (which could also serve to attenuate the fan noise). Because I am less interested in keeping things compact, this should not be a problem.

As for drawing, its what I do best, or I can whip it all out in 3D (using CAD software)… no problem.

BTW, your drawing looks really good… reminds me of Stonehenge… very temple-like.

Thanks very much for your offer to help.

Could you send the list of “Approved Parts” (and where to get them) for construction of a pair of standard Melquiades.

You can send it here :

Thanks very much,
